Abstract: Electronic packaging films, tapes, bags and pouches having excellent optical properties and heat sealability, low hexane extractables and a good balance of physical properties may be prepared from linear low density polyethylene having a melt flow ratio (I21/I2) from about 23 to about 32, prepared in a tandem dual reactor solution phase polymerization in the presence of a phosphinimine catalyst and a co-catalyst system which comprises an aluminum based co-catalyst, an ionic activator or a mixture thereof.

Abstract: Food packaging films, bags and pouches having excellent optical properties and heat sealability, low hexane extractables and a good balance of physical properties may be prepared from linear low density polyethylene having a melt flow ratio (I21/I2) from about 23 to about 32, prepared in a tandem dual reactor solution phase polymerization in the presence of a phosphinimine catalyst and a co-catalyst system which comprises an aluminum based co-catalyst, an ionic activator or a mixture thereof.

Abstract: Medical packaging films, bags and pouches having excellent optical properties and heat sealability, low hexane extractables and a good balance of physical properties may be prepared from linear low density polyethylene having a melt flow ratio (I21/I2) from about 23 to about 32, prepared in a tandem dual reactor solution phase polymerization in the presence of a phosphinimine catalyst and a co-catalyst system which comprises an aluminum based co-catalyst, an ionic activator or a mixture thereof.

Abstract: Bags, other than food contact or medical bags, having a good balance of properties may be prepared from linear low density polyethylene having a melt flow ratio (I21/I2) from about 23 to about 32, prepared in a tandem dual reactor solution phase polymerization in the presence of a phosphinimine catalyst and an aluminum based activator in the first reactor and an ionic activator in the second reactor.
